Perimeter temperature controlled heating and cooling system


A temperature controlling system for buildings is provided. A temperature conditioned perimeter cavity extends around the structure and maintains desired temperature within the structure. The perimeter cavity is insulated and provided an energy storing medium of air, fill material or baffles. The perimeter cavity is temperature conditioned by transfer of energy to the perimeter cavity, particularly by exchange from the perimeter foundation below the perimeter cavity, by geothermal exchange from a below ground energy storage container or energy collecting probe, or a combination of both. The system is applied to a grain silo having an insulated first grain silo forming an outside wall member and a smaller circumference second grain silo forming an inside wall with a temperature conditioned perimeter cavity defined between the two grain silos.

PRIORITY CLAIM

The present application claims benefit of priority of U.S. Provisional Application No. 61/415,403 filed on Nov. 19, 2010. Also, the present application is a continuation in part of U.S. application Ser. No. 12/074,663 filed Mar. 5, 2008, which claims benefit of priority of U.S. Provisional Application No. 60/904,877 filed Mar., 5 2007.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a method and system of controlling the temperature of a building by creating a temperature conditioned perimeter around the extents of the structure and, particularly where geothermal exchange or manipulation of the perimeter foundation of a structure is used to condition the perimeter area.

2. Background

In modern times, it is quite rare to find a home that does not have some sort of heating and cooling system. There are many different types of heating and cooling systems, and the mechanism by which heat is transferred to or from the living environment varies considerably. For these homes that utilize these systems, there are many different factors that determine which one to choose and many consumers must compromise due to the limitations of each.

The standard heating or cooling system takes in air (either from outside or re-circulated), conditions it (by raising or lowering the temperature), then forces the air back into the building\'s interior. The interior temperature then adjusts accordingly. To maintain this difference in temperature and improve efficiency of the heating and cooling systems, the standard method is to insulate the building with insulating material inside the walls, as well as sealing any openings (doors, windows, etc.) to let the least amount of air pass through. The air on the inside of the building is then treated in order to raise or lower its temperature. The result is a temperature gradient between the inside and outside of the building.

There are several disadvantages to the standard heating and cooling methods. Efficiency and uniformity of the interior temperature are the primary issues that face building owners. Hot or cool spots within a home or office are very common and, oftentimes, unavoidable without extensive ductwork and/or additional heating/cooling systems. There are many alternatives available to consumers but they bring about other issues, as well. There is especially the need to have a system that is easily maintained and standard enough to be repairable by most heating and cooling system technicians. It\'s not preferable to have a system that would require a specialized technician that would perform maintenance or service work on the system.

Efficiency is most affected by the heating or cooling unit itself and the degree of insulation in the building. Many new heating/cooling units are designed with outstanding efficiency in mind as long as they are properly maintained. The problem is typically not with the unit itself, but with the insulation and the inevitable heat transfer between areas of two highly different temperatures. When properly installed and with high quality parts, a building\'s heating/cooling system can run very efficiently. However, when dealing with large areas or extreme temperatures, it takes a lot of energy to change the temperature even a degree warmer or cooler and it takes a longer time to do so. When temperatures are at their extremes is when utility bills tend to get higher and heating/cooling systems work the least efficiently. At this point, the building owner is faced with high utility bills and, oftentimes, decreased performance of the heating/cooling system.

Geothermal heat pumps are a fairly modern development that have brought forth efforts to harness the energy of the earth to assist in more efficiently heating and cooling homes. At an average depth of around eight feet beneath the earth\'s surface, there exists a layer of earth that, due to thermal inertia of the earth, holds a fairly constant temperature year round. This temperature varies due to location on the earth but, for a particular area, holds fairly constant. Currently, the primary means of employing this constant temperature level has been to operate heat pumps that use this level for heat exchange. In the summer, this level is typically cooler than the surface air temperature and, in the winter, this level is typically warmer than the surface air temperature, thereby increasing efficiency of the heat 3 pump. The main problem with a geothermal heat pump is the digging and work required to properly utilize this constant temperature level. Initial cost is high but the payoff in the following years is quite amazing.

Overall, it is the object of this invention to devise a heating and cooling system that is efficient and provides the most comfortable environment with a stable interior temperature by providing an insulating layer around an entire structure that is also temperature conditioned.

SUMMARY

OF THE INVENTION

The present invention creates an improved system of climate control over the traditional heating and cooling systems. The invention can be described well by narrowing the field of view to a single roomed building. In a preliminary embodiment, a forced air heating and cooling system is located outside of the building. Essentially, the conditioned air is blown throughout a cavity that encompasses the entire building and can even extend many feet beneath the building. Thus, one objective of the present invention is to maintain the air in this perimeter cavity at a particular temperature. By doing so, the temperature of the interior room space is also maintained at a comfortable level without blowing heated or cooled air into the room itself. Essentially, these air cavities, coupled with other insulating material, work to give the building even more insulating potential and provide a more stable interior temperature.

Another object of the invention is to maintain temperature in the perimeter cavity by transfer of energy from a below ground energy storage container, whereby geothermal energy can be used to control temperature of a room through control of the perimeter.

Another object is the transfer energy to the perimeter cavity using a below ground probe with energy conducting extensions to transfer geothermal energy to control the temperature of the room or perimeter cavity.

Another object is to store energy within the perimeter cavity for a longer period of time and stabilize the temperature therein using a series of baffles built into the space of the perimeter cavity to store energy and slow the dissipation thereof.

Another object is to create a perimeter cavity about a building using a plurality of panels that are attached to the exterior of a building. These panels may be retrofit to an existing building or incorporated into the construction of a new building. These panels may further provide enhanced insulation on their exterior surface to reduce energy transfer from the perimeter cavity to the outside environment.

Yet another object is to manipulate and control the temperature of the perimeter cavity by conditioning the temperature of the foundation material below the perimeter cavity or providing a source of heat below the perimeter cavity that will rise into the perimeter cavity.

These and other objects of the invention will be apparent to those skilled in the art and should be considered within the scope of the claims that follow.
